Too funny!! I remember hearing that bizarre story. Patterson is in New York state...which is not New England...just abuts NE states....not that that matters...
Perhaps the dog got a lot of attention at the hall...maybe people brought him treats. That would account for the meeting time excitement. Other than that dogs can be creatures of habit...so perhaps it was just his routine. Or perhaps the story is just a fairy tale.
At any rate, that was a spiritually minded dog. How happifying.
